A 24 year old male television cable installer was electrocuted when he came in contact with a 7280 volt powerline running 5 feet above the roof of a house. The employer was an electrical contractor with 90 employees who had been in business for 12 years. The company president served as the safety officer. The company did powerline work, TV cable installation and other electrical contracting. Safety information was primarily conveyed via on the job training, supplemented with safety materials. The company did not have a formal safety program. Before beginning the contract to install TV cable in a semirural area, two safety evaluations of the project had been conducted, one by the local power company and the other by a private concern. The victim, part of a ten person crew, had climbed onto the roof of one of the houses to resecure a cable dolly onto the hanger wire line from which it had fallen. While on the roof, the victim's head contacted a 7280 volt powerline approximately 5 feet above the roof. The position of the powerline in this case had been in violation of the code which states that powerlines be at least 6 feet horizontally away from and 12 feet above the rooftops of buildings. It was recommended that all code violations be corrected within a reasonable time and that safety training be a part of new employee orientation.
